推荐答案

分配一个新的 图片 对象 PictureBox 的图像属性。要从文件加载 Image ，您可以使用 Image.FromFile 方法。在您的特定情况下，假设当前目录是 bin 下的目录，这应该加载图像 bin / Pics / image1.jpg ，例如：

Assign a new Image object to your PictureBox's Image property. To load an Image from a file, you may use the Image.FromFile method. In your particular case, assuming the current directory is one under bin, this should load the image bin/Pics/image1.jpg, for example:

pictureBox1.Image = Image.FromFile("../Pics/image1.jpg");

此外，如果这些图像是静态的并且仅用作应用程序中的资源，则资源将是比文件更合适。

Additionally, if these images are static and to be used only as resources in your application, resources would be a much better fit than files.
